Y., A conrona'rrogr INDUSTRIAL TRUCKApplication filed November Heretofore difficulty has existed in this'type of device due to leakage of theV soap emulsion at the union of thesoap frame and the truck and in many cases frames composed of separatesides have been used, multiplying the leakage opportunities. In ordinarypractice the soap emulsion contains caustic soda which acts to expandthe emulsion body and further increase thedifliculty in providing asuitable seal for the assembled parts. Y

It is one of the aims of the present invention to minimize theopportunity for leakage and provide a light-weight, sturdy truck Withwhich a soap frame may be quickly and conveniently associated for thereception and molding of the soap emulsion and from which the soap framemay be easily removed after the emulsion has solidified.

Another object of the invention is to provide a truck frame `and moldingbottom substantially of pressed metalcorrelated with Wheeled axles andclamping means for the soap frame whi in construction and inexpensive.

Another object is to provide an elfective means for preventingdisplacement of the formed cakes after the molding frame or box has beenremoved and while the truck is subject to the shocks and movements oftransportation.

Still another object is to provide a truck having a combined underframeand false bottom which may bequickly and convenientlyV modified by theinterchanging of the false bottom for one of varying size, and in whichclamping means are provided which are adjustable or easily alterable toaccommodateV tion hereinafter set forth and the scope of the ch shall berelatively simple i2, i931. ySenat Nol 574,565.

ing a horizontal flooring 11 and aV marginal depending flange A12which:is slightly vinturned atthejbottom as indicated at 13. Endv braces 14connect the llower side of the horizontal .flooring withY the inturnedportions 13 of the'ilange12- Sidev braces 15 correspondingly extend fromthehorizontal flooring of the underframe to the inturned` portions 13ofthe depending :,lange'12. Spaced lugs 16 are welded to thetop ofthehorizontal flooring for purposes which will more fully hereinafterappear. `Spacedpedestals 20 preferably ofpressed metal are riveted totheflooring and depend therefrom, each being substantially cut away at 21to lighten the construction. Bolted to the lower side of the pedestals2O are axles 22 havingsuitable wheels 23 at either end thereof. Thesewheels may be of the bearing type kas desired.

Mountedon the underframe is a molding elementin the forni of a falsebottom 24 coinprising a pressed .steel member spacedl from theunderframe flooring 11 by central andV marginal timbers 25 and 26,respectively. The false bottom` has a horizontal floor 27 andrraisedmarginal regions 28vdefiningv a shoulder 29 between the flooring andraised marginal regions. The' edges of the false plain or anti-frictionY Fig. 2 is a view in side elevation of the soapl i truck shown in Fig.V1, parts of the end of i bottom areY formed by extendingthe sheet metaldownwardly from the raised/marginal vregions in the manner of averticaledge or wall 30 until icontact is made' with the flooring of theunder-frame.'

sheet metal ooring, the marginal regions, y

the central and marginal timbers and the flooring of the underframe. Bythe removal of these bolts and the substitution of a similarlykconstructed false bottom of dilerent width the truck may be' modified tomoldy soap cakes of another size and as will appear hereinafter, theclamping devices used are arrangedjfor adjustment to operate on thedifferentl sized soap frame. 'This will involve, of course, the drillingof another series of holes in the underframe flooring for accommodationof the stove bolts. Y

Preferably the soap frame employed with the present truck is of the unitbox type rather than the separable wall construction. The lower part ofsuch a `box is indicated at 40 and the opposite walls may be slightlytapered inwardlyand upwardly to facilitate removal of the soap frameJfrom the molded cake.k Along each sidewall of the box an angle iron 41isv secured havingkthe lower `surface of one angle face inralineinentywith the lower edge "ofthe box. The soap frame is open at top and bottomand may be mounted on the underframe exteriorly of and adjacent to theedges 30 of the false bottom. A 'close Contact is eilec'ted andl wherethe box kemploys the tapered walls described the soap frame ispractically wedged over the false bottom. Clampinfr' devices 50 areprovided on opposite sides or the underframe inthe form of boltslfhav'ing, Shanks extending through the lower part of the side braces 15and upwardly through apertures 54 in the underframe `flooring 11. Eachbolt is provided with a'n'ut 55 anda lock nut 56 at its lowerend and atits upperend is provided with an' offsethe'ad 57 yadapted Vto be 'swunginto or out of engagement with the outwardly extending flanges ofthetan'gle iron `41. Tightening the nut 55 `sets the odset head 57 downsecurely against'the angle iron, clamping the soap Vframe -to theunderframe'looring with the wooden or composition walls of the soap'frame in close engagement with the side edges of the false bottom 24.This effectively associates the soap `frame-with the truck in such amanner as to prevent vthe leakage of the soap emul- 'sion even underlthe expanding influence of Ithe caustic soda or other chemicalsemployed. Y Y

Another Vseries of bolt holes is provided through the underframeflooring and side braces 15'as Vindicated at 60. These are set inwardlyVfrom the sides of Ythe truck frame beyond the -bolt holes '54` so thatwhen the :truck is modified to take a narrower bottom molding elementthe bolts 5() are removed 'from their positions in the holes'54 and'inserted in the holes 60. Y

VAt each end of the truck an aperture is provided in the flooring 11and-depending flange 12 as indicated at 70.v Across this aperture a bar71 extendsand is welded in fthe angle formed by the flooring and flange.

tom or lower molding element. In using a tapered box as previouslydescribed, for draft purposes, there is a wedging action which makes fora tight union of the box and falsev bottom. A

YIn building or reconstructing the trucks for soapl ramesnarro'wer thanthe one shown vin Fig. 3 of the drawing, al narrower Jfalse bottom 72 isbolted to the underframe Hooring (see Fig. 4) and the clamping bolts 50are located in holes where the offset heads are adapted to be swung intoengagement with the angle 'irons of the narrower soap iframe. The extraseries of holes for the stove bolts which secure the false bottom inposition may be originally provided for alternative assembly of thebottoms or they may be made at the time of reconstruction.

In using the above described truck the soap frame bordered at itsloweredges with the angle iron construction 41 is applied over the false`bottom 24 with its tapered walls closely itting the edges of the falsebottom. To provide for this assembly the offset heads 57 of the bolts 50are swung out of the way and are later restored to position over 'theprojecting lower flanges of the angle irons. "When the "soap frame isthus applied the spaced lugs 16 on opposite sides ofthe underframeflooring assist in locating the soap frame' and the angle members `atthelower part thereof lie within the spaced lugs. The nuts 55 are thenscrewed up on lthe bolts, iirmly clampingl the soapV frame totheunderra-me flooring adjacent the edges of the false bottom or lowermolding element. The lock nuts 56 are then operated' to hold Vtheboltsin position. lVith the soap frame assembled a soap emulsionisvpoured into the cavity formed by the false bottom and the soap frame.This emulsion eventually cools andl solidifies whereupon the clampingdevices are loosened and the molding box removed from the'truck.

The molded soapv cake is 'retained on the truck 'seated on the falsebottom andheld against slipping or dislocation by the engage'mentot thelower part of the soap calze with the depressed portion of the falsebottom 24. The truck may then bel moved to another station where thelarge cake'is subjected to other treatments eventually dividing it intoa multiplicity of' small commercial units.
